How do subscores on the ACT apply to admissions?

My highest ACT score is a 31, with subscores of
English: 34
Reading: 33
Science: 30
Math: 27
I’ve gotten a 27 on math EVERY TIME I’ve taken the act… lemme tell ya! Like sheesh. Now, if I wanna go to a school like UCLA for biochemistry, will my fairly low math score be a red flag? HELP
